Because the statement is a good joke, but only as far as its accurate.
The joke would be good if US politicians wasn't Politicians, but real Statesmen instead.
A queen/king/president/politician, as a Statesman should:
1. Engage in warfare & conflict
2. Engage in diplomacy, at the relevant levels
3. Further the interests of her state or her people
Star losing 50% of her wand isn't like losing access codes to Nukes, its like losing all the brains(schematics, persons, education, theory) needed to build Intercontinental Atomic Cruise Missiles.
Sure, you got what you have, but you can't really reverse engineer them, repair them or build more.
